Can' connect with Intel wireless 3945ABG and Knopppix 5.3.1
Hi,
I'm not expert both of wireless networking and Knoppix/Linux.
I'm getting crazy trying to setup internet connection with my wireless card
Intel Wireless Pro/3945ABG and last Knoppix 5.3.1 DVD.
It seems card is detected, but I'm not able to get IP address from my router with DCHP enabled.
And still, I'm not able to ping any host even if I try to disable DHCP.
Below you can find printout of commands iwconfig, ifconfig (in case of attempt with DHCP enabled), and lsmod.
Please, help me! Thanks!

Re: Can' connect with Intel wireless 3945ABG and Knopppix 5.
According to your iwconfig listing, it seems to me that your setting to the wireless is there. But then on your ifconfig listing, it shows the wireless device has not been activated.
First try out the following:
Code:
# ifconfig wlan0 up
# pump -i wlan0
If the above fail, try to disable the encryption on your wireless router, and try again. The objective on this step is trying to isolate the potential problem area (i.e. the encryption part).
If you cannot make the wireless works on a encryption free network, try to use the ndiswrapper method. You may find it helpful by reference to http://www.knoppix.net/wiki/Network_FAQ question 2, 11, 12, 13 for detail steps.
When your wireless connection passes the above step, then move on to the encryption part.
Good luck. If possible, you are more than welcome to report your successful story here so other users can be benefit from your experience.
